Hey, Ana! Welcome to PC! Don't worry about your grammar. I can understand everything so it's all good. If you want to learn more about Pokemon, there's so many sections from Pokemon Gaming Central-Pokemon General all filled with theories, reviews, opinions and anything. I've learned a lot about X & Y, by just being involved with the community.
As for the making friends part, there's so many people on here who you can talk to and they would love to chat. I've seen it first hand. Just message anyone with hey, and I'm sure you could get a conversation going pretty quickly. This is the Internet. We don't judge. Don't be shy!
Anyways, if you need any help, pm a Moderator, Super Moderator or Administrator. There names will be bolded blue, bolded orange or bolded red. I hope you make a lot of friends here, Ana. And, if there's anything that I can get you, let me know (:
